In a decision that could reshape the rules for online consumer reviews, a Virginia court has ruled that the popular website Yelp must turn over the names of seven reviewers who anonymously criticized a prominent local carpet cleaning business.

The case revolves around negative feedback against Virginia-based Hadeed Carpet Cleaning. The owner, Joe Hadeed, said the users leaving bad reviews were not real customers of the cleaning service — something that would violate Yelp’s terms of service. His attorneys issued a subpoena demanding the names of seven anonymous reviewers, and a judge in Alexandria ruled that Yelp had to comply.
